Bree, I study physiognomy a lot. I love to draw and paint. I don't want to be mean or anything, but there are very few CDs who can pass fully as women,
under close scrutiny. There are many subtle gender cues (brow, chin, face width, distance between various points on the face, neck width, shoulder size, etc), outside of the more obvious gender cues such as hair length and style, the presence of breasts, and makeup. This is why many TSs who wish to live as women full time and not be read, opt for FFS on top of the effect of the feminizing hormones.
A GM might have a chance passing fully at all angles if he has a small stature, small hands and feet, small neck and shoulders, and is very young, and he doesn't have a classic male forehead or chin.
Still, most people do not look closely at passers-by, providing there is nothing in their peripheral view that raises flags, and judging by your avatar, you don't raise any. You look very nice.
